That's great if they let you. Most (at least around here) wont let you anymore.
And the "most" didn't make this decision on a whim. I've posted this before, but some may have missed it, so I'll post it again here.
"Revolvers vs Semi-Automatic Pistols for Police Service"
Let me begin by stating that I love revolvers, but, the fact is, the revolver's day is over as the best choice for a service weapon.
I retired from the New Jersey State Police in 1991, so I was around during our transition from revolvers to semi-automatic pistols with over half my career being in the revolver era. The last two incidents in which Jersey Troopers were shot while armed with revolvers (and which prompted our switch to the H&K P7M8 in 1982) both involved lone troopers facing assailants (in one case, multiple assailants) armed with high-capacity semi-automatic pistols. Both troopers emptied their six-shooters and both were shot and incapacitated (one seriously wounded and Trooper Phil Lamonaco fatally wounded) before they were able to reload.
It is fun to wax nostalgic about the "good old days" of revolvers, but any advantages they may have are far outweighed by the cold facts that their ammunition capacity is minimal and they are just too slow to reload under fire compared to the semi-automatic pistol. It is a virtual certainty that as a police officer today, if you have the misfortune of facing armed criminals, you will be facing one or more assailants armed with high-capacity semi-automatic pistols. No matter how proficient you may be with a revolver, this is not a good situation to be in.
I would no more want to be a police officer armed with a revolver in today's world than I would want to be armed with an '03 Springfield bolt-action rifle in a modern combat environment. The term "under-gunned" describes a real world situation and it is for valid, life-and-death reasons why today's police forces are almost universally armed with semi-automatic pistols.
The new Smith & Wesson 7 and 8 shot revolvers help to level the playing field a bit, but if I were to put on the uniform again, I would be holstering my Heckler & Koch P30LS .40 S&W or some other tried and true semi-automatic pistol.
***Note***
Please don't view this as a criticism of anyone's decision to carry a revolver. It isn't. We are all adults here and we all make our own choices for our own reasons. I am simply stating that I strongly believe the professional law enforcement officer is best served and most capable of protecting themselves and the citizens they are sworn to protect by arming themselves with a high quality semi-automatic pistol.
